Communications system, apparatus and method

ABSTRACT

The present invention relates to a communications system (100), comprising: one or more communications networks (104); a plurality of content items accessible over said one or more communications networks; and a data store (110) of presentation configuration data for one or more of said plurality of content items for defining presentation of a content item corresponding to presentation configuration data. The present invention also relates to an apparatus and method.

FIELD

The present invention relates to a communications system, apparatus and method. In particular, but not exclusively, to a communications system comprising a plurality of communications networks.

BACKGROUND

The distribution of media content such as music and video now takes place over various communications channels. For example, music and video may be broadcast over terrestrial VHF and UHF networks to be received by television sets, from satellite to ground stations or domestic satellite receivers and over cable networks. Such broadcast services generally comprise one or more communication channels, each channel comprising a particular carrier frequency onto which is modulated a signal representative of the content to be transmitted over the channel. Content, typically television programmes, films or music shows, are transmitted over a particular channel or channels at particular times in accordance with a programme schedule. In this regard, broadcast services comprise “appointments to view” whereby a viewer has to tune into a channel at the time content of interest to the viewer is transmitted on that channel.

More recently, interactive television has become available whereby a viewer, prompted by a message displayed on the television, may send control signals or messages to the broadcaster or third party associated with the broadcaster and displayed message to initiate certain activity. For example, to initiate selection of a programme to view or receive information about a programme.

Broadcast services are widely available using digital communications techniques. Digital broadcast service providers often provide data to populate a menu or Electronic Programme Guide (EPG) of, for example, a set-top box or television with suitable EPG software, on one of their channels. A typical EPG is based on a grid system and displays programmes and channels in transverse directions. For example, the programmes for a particular channel may be displayed in a horizontal direction with different channels set out in a vertical direction. A viewer may use a remote control having “UP/DOWN” and “LEFT/RIGHT” buttons and use these buttons to move a cursor about the display to highlight programmes. A viewer may select a highlighted programme by actuating a “SELECT” button which tunes the receiver to the particular cannel. Optionally, a viewer may highlight a programme which is to be broadcast in the future and selection of that programme may invoke a “record” or “reminder” option.

Television viewers are generally familiar with EPGs set out in a grid system and navigable using remote control devices having relatively simple buttons such as “UP/DOWN” and “LEFT/RIGHT” buttons and “SELECT” buttons.

Content is also available over computer networks such as the Internet. Content is usually accessed over the Internet using a personal computer such as a desktop or laptop computer. The location of content on a network such as the Internet is defined by a network address known as a Uniform Resource Locator (url). A particular content item can be addressed and downloaded to the computer addressing the content for later presentation or may be “streamed” whereby the computer presents the content as it is provided over the network. The user interface for a computer is generally a pointing device such as a “mouse”, and computer users are familiar with a user interface which allows for the pointing device to be moved on to an icon, text (such as an Internet “link”) or other graphic displayed on a display and selecting that graphic to invoke a function associated with the graphic, for example addressing content over the Internet.

Many communications networks, including those making up at least a part of the Internet, are configured to transmit large amounts of data and these are sometime termed “broadband” networks. For the purpose of this description the term “broadband network” is used refer to a communications network or part thereof which is capable of transmitting content items such as video and music in an acceptable timeframe. Such networks may also support music or video streaming. The data bandwidth capability of a consumer connection to such a network is typically at least 2 MBit/s.

Many computer users have computers which are part of a local area network (LAN), for example in their workplace and increasingly at home in their domestic residence. Users often keep content items on memory storage coupled to their LAN and accessed through their computers.

Aspects and embodiments of the present invention were devised with the foregoing in mind.

SUMMARY

Viewed from a first aspect the present invention provides a communications system, comprising one or more communications networks and a plurality of content items accessible over said one or more communications networks. A data store of presentation configuration data for one or more of said plurality of content items for defining how a content item associated presentation configuration data will be presented is also provided.

The presentation configuration data may consist of a series of rules or definitions which determine how a content item to which that presentation configuration data relates will be displayed on a display screen or presented on some other presentation device. In one embodiment of the invention the presentation configuration data comprises rules and/or instructions for presenting a content item with indicia such as logos or graphics.

In a one embodiment a content item representation configuration module operative to define representation of a content item in dependence on presentation configuration data corresponding to said content item is provided. The content item representation configuration module provides control signals for a display to display a content item in accordance with its associated presentation configuration data.

The communications system may further comprise a content item receiver operative to access said plurality of content items over said one or more communications networks, wherein said content item representation configuration module is operative to define representation of a content item according to said presentation configuration data responsive to said content item receiver accessing said content item. In such an embodiment the presentation of a content item is configured when a content item is accessed.

Suitably, the content item is presented on a display device and said content item receiver is operative to drive said display device to display said content item in accordance with said presentation configuration data.

Typically, one of the communications networks is a broadcast communications network and said presentation configuration data comprises broadcast communications network display data for displaying indicia associated with said broadcast communications network. One example of such indicia is a channel number or logo.

The content item representation configuration module may be further operative to define representation of a content item in dependence on a state of the content item receiver and presentation configuration data stored in the data store corresponding to that state. For example, presentation configuration data may be selected for displaying a channel number or logo corresponding to the broadcast channel to which the receiver is tuned.

In an embodiment said presentation configuration data comprises content item owner presentation configuration data usable by said content item receiver for displaying indicia associated with said content item owner. For example, the content item owner presentation configuration data may include a graphic such as a logo or trade mark for the content owner.

The presentation configuration data may also comprise original equipment manufacturer (OEM) configuration data usable by said content item receiver for displaying indicia associated with the manufacturer of the content item receiver, such as a logo or trade mark of the OEM.

The content item representation configuration module is operative to transmit content item configuration data to said content item receiver. Such an arrangement may allow for the content item representation module to be separate from the content item receiver such as located remote and in communication with the content item receiver over a communications network.

A further one of said one or more communications network is a broadband network such as the Internet and the content items may be accessible over the Internet and form a part of the so-called world-wide web. The content item accessible over said broadband network may comprise a broadband content item such as music or video.

The presentation configuration data for said broadband content item comprises presentation configuration data usable by said content item receiver for displaying indicia associated with a source and/or originator of said broadband content item. Thus, the brand or commercial identity of the content item owner may be displayed thereby maintain and/or creating a relationship between the content item owner and the viewer.

A yet further one of said one or more communications network is a local area network. For example, a network in a domestic residence on which a viewer may store content such as personal videos and photographs.

In one embodiment the data store is accessible by one or more of content owners, OEMs, broadband service providers and/or broadcast service providers for configuring said data store with presentation configuration data. This provides a mechanism for content owners, OEMs, broadband service providers and/or broadcast service providers to set up presentation configuration data.

Suitably, an interface may be provided which is operative to provide a communications conduit to said data store for said one or more content owners, OEMs, broadband service providers and/or broadcast service providers for configuring said data store with presentation configuration data. The interface may be a network interface which provides a mechanism for remote network based setting up of presentation configuration data in the data store.

Viewed from a second aspect the present invention provides content item display management module, comprising:

-   -   a data store of presentation configuration data for one or more         of a plurality of content items; and     -   a content item representation configuration module operative to         define representation of a content item in dependence on         presentation configuration data corresponding to said content         item.

The content item representation configuration module may be further operative to define representation of a content item in dependence on a state of the content item receiver and presentation configuration data stored in the data store corresponding to that state. For example, said presentation configuration data may comprise broadcast communications network display data for displaying indicia associated with said broadcast communications network. The display indicia may be a channel number or logo of the channel to which the receiver is tuned. The receiver may be a television receiver or a so-called “set top box” for a display which may be tuned to channel frequencies for receiving broadcast communications.

The presentation configuration data may also or optionally comprise content item owner configuration data usable by said content item receiver for displaying indicia associated with said content item owner and/or original equipment manufacturer (OEM) configuration data usable by a content item receiver for displaying indicia associated with the manufacturer of the content item receiver.

Suitably, the content item representation configuration module is operative to transmit content item representation data to a content item receiver. Thus it may be located remote from the receiver.

In an embodiment said data store is accessible by one or more of content owners, OEMs, broadband service providers and/or broadcast service providers for configuring said data store with presentation configuration data.

The content item management module may further comprise an interface operative to provide a communications conduit to said data store for said one or more content owners, OEMs, broadband service providers and/or broadcast service providers for configuring said data store with presentation configuration data. Said interface may comprise a network interface thereby to provide said content item owners with remote access the data store.

Viewed from a fourth aspect the present invention provides a content item receiver, configured to receive content item representation data and drive a display device to display indicia corresponding to said content item representation data. The receiver may be a separate unit to the display or integral therewith.

Generally, the content item receiver is further configured to drive a display device to reserve one or more regions of said display for indicia corresponding to respective content item representation data.

Typically, the content item representation data corresponds to one or more of: a content provider; a content owner; a service provider; a broadcast network owner; and an OEM.

Viewed from a fourth aspect the present invention provides a method of content item display management, comprising:

-   -   storing presentation configuration data for one or more of a         plurality of content items; and defining representation of a         content item in dependence on presentation configuration data         corresponding to said content item.

Viewed from a fifth aspect the present invention provides a method of operating a content item receiver, comprising receiving content item representation data and driving a display device to display indicia corresponding to said content item representation data.

Viewed from a sixth aspect the present invention provides a computer program comprising computer program element operative in a data processing apparatus to implement the content item display management module and/or the content item receiver and/or the method as set out above.

Typically, there is provided a carrier medium carrying a computer program as set out above. The carrier medium may be any suitable medium, for example an electronic signal, an optical or rf carrier signal, magnetic media and digital versatile disk.

A detailed description of one or more embodiments of the invention follows with reference to the figures provided.

FIG. 1 schematically illustrates components and communication links of a system 100 for providing access from one or more content receivers to content from a plurality of sources. The system 100 comprises a plurality of content sources 102 arranged to distribute content for reception by a plurality of content receivers 108 (e.g. set-top boxes) and subsequent viewing of the content on a display associated with the respective receivers 108 over at least one of a communications network 104 (such as: a wide area network (WAN), e.g. the Internet; local area networks (LAN); or a combination of two or more such networks) and a broadcast video distribution network 106 (e.g. a terrestrial cable IPTV or satellite television broadcast system). The system 100 also comprises a media display management server (MDMS) 110 which controls content configuration and distribution of content to the content receivers 108 and provides a content search and/or discovery and/or navigation module and other services. The MDMS 110 provides a content management environment responsible for the presentation of the content accessed by content receivers 108 (or users thereof) registered with the MDMS 110, giving users a consistent, quality controlled, user interface experience across multiple content types such as broadcast TV, interactive content, and Internet video content.

A media display management module (not shown) is provided in the content receivers 108 for managing the content search, discovery, navigation and presentation on the content receivers 108. The media display management module is configured to communicate with the MDMS 110 over the communications network 104.

The MDMS 110 and the media display management module configure content for display based upon a set of parameters specified by one or more of: a content provider; a user of a content receiver 108; a content receiver 108 manufacturer; and a service provider. The parameters may be embedded as operating parameters of a content receiver 108.

FIG. 2 schematically illustrates the features of FIG. 1 in more detail and provides an overview of the functional elements and modules of the MDMS 110. The features illustrated in FIG. 2 which correspond to features already described in relation to FIG. 1 are denoted by like reference numerals.

In the illustrated embodiment, the MDMS 110 offers a client-server relationship with content receivers 108 comprising TV devices (such as set-top boxes), or as a web service via device Application Programming Interfaces (APIs) to TV devices and other systems. Content receivers 108 comprising TV devices that connect to the MDMS 110 may have embedded in them a content receiver specific client (e.g. media display management module) that enables at least a portion of platform services of the MDMS 110 and content owner and original equipment manufacturer (OEM) branding, i.e. branding for the content receiver, manufacturer or supplier, to be maintained uniformly across device types. Once ported, code changes may not need to be made to the device software to add additional content, features and branding.

For content receivers 108 that connect to the MDMS 110 and which do not have embedded client software, the platform services and content can be enabled via direct services application program interfaces and a TV device user interface. In these instances, a sub-set of the full platform functionality may be used, and content owner and OEM configured branding and services may not be fully-reflected in the interface displayed to the user because of the limitations thereof. However, certain minimal elements may be required to be supported as a condition of utilising the APIs.

Internet video traffic delivered to TV devices does not pass through the MOMS 110, but utilises the direct streaming services, protocols, codecs and networking paths from the content owners to the TV devices. While these services, protocols, codecs and the networks utilised are common to Internet video streaming to PCs, TV receivers may only be capable of processing a subset of these protocols and codecs.

Likewise, broadcast content delivered to TV devices does not pass through the MDMS 110 either, but is subject to broadcasting protocols and transmission paths common to broadcast of TV signals to TV devices over suitable media (e.g. Satellite, Antenna, and Cable).

Using the MDMS 110, content owners and media aggregators (i.e. parties who aggregate syndicated web content such as news headlines, weblogs (blogs), podcasts, vlogs (video blogs) in a single proposition) can register and manage their services and content for discovery and use by content receivers 108 configured to receive content made available through the MDMS 110. Content owners can also configure additional products and services via the MOMS 110 such as content subscriptions and promotions and their content owner branding and interactive options are preserved across all devices wherever their content is displayed.

A content receiver user having content stored on their own local content domain may also be able to register and manage content stored on that local content domain using the MDMS 110, and for discovery and use using their content receiver. In this case, the content receiver user is effectively another content owner.

The MOMS 110 implements a range of functions, namely:

-   -   a. The registration of Internet video sources and libraries to         enable the search, discovery, navigation and playing of content         on multiple TV device types;     -   b. The registration of interactive destinations and TV         applications to enable their search, discovery, navigation and         access on multiple types of TV device;     -   c. The management of content branding, media searches,         recommendations, interactive links and promotions for content         owners (including advertising and sponsorships) such that the         correct branding and facilities are displayed to the viewer         whenever their content is being accessed, across multiple types         of TV device—this capability is common to TV broadcasters,         Internet video aggregators, and interactive application owners;     -   d. The registration of “users”—such as TV viewers, and the         management of their personalisation information, such that a         viewer's identity and personalisation information is available         across multiple types of TV device;     -   e. The provision of a range of content discovery services, such         as:         -   i) Centralised search across all content;         -   ii) Content recommendations;         -   iii) Content sharing between community members;         -   iv) Content promotion for content owners;         -   v) Resolution of TV Keys™     -   f. The implementation of distribution arrangements and rights         restrictions for content owners, particularly the enforcement of         territory rights restrictions.     -   g. Centralised subscription payments services and micro billing         (billing for individual content items) for all content owners;     -   h. Advertising services which may comprise a range of products,         for example:         -   i) “click through” advertising links to video or interactive             destinations;         -   ii) Insertion of video advertising in playlists and video             content consumption;         -   iii) Interfacing to standard 3^(rd) party Internet ad             serving infrastructures and campaign management and sales             facilities; and         -   iv) The provision of viewer targeting data to 3^(rd) party             ad serving engines.

FIG. 3 schematically illustrates the MDMS 110 and components thereof according to one or more embodiments of the present invention.

The MDMS 110 includes a network interface 112 providing a route through which the MDMS 110 is coupled to the communications network 104. The MDMS 110 communicates with the content sources and content receivers over the communications network 104 via the network interface. Content received at the MDMS 110 from the content sources may include, for example, content metadata to feed a search and retrieval module (e.g.

Web feeds such as RSS XML feeds), content owner branding data for application to content to be displayed, other content owner rules relating to display and consumption of their content.

A content owner configuration module 114 of the MDMS 110 is configured to provide a mechanism for content owners to register and manage their content. The content owner configuration module 114 comprises a processor and a data storage module.

When initially registering their content with the MDMS 110 to make such content available to viewers having content receivers configured to receive such content via the MDMS 110, content owners conduct a set-up process using the content owner configuration module 114. This set-up process may be conducted by the content owner, perhaps at a remote location, by way of a content owner terminal, for example, a PC, arranged to communicate with the content owner configuration module 114 via the communications network 104 and network interface 112.

In an example, the content owner could use the PC to navigate to a specific web-page to initiate the set-up process. The content owner configuration module 114, upon receiving a request for the web-page data from the PC, transmits the relevant web-page data to the PC of the content owner to allow the content owner to conduct the set-up process. The content owner is presented with a content owner interface which displays a number of functions relating to how it wishes to configure its content. In this regard, the content owner can define:

-   -   Its MediaRSS feeds and associated parameters that will be         retrieved by the content indexer 118. This is so that the         content owners content items can be presented to a user in         search results and recommendations when they are relevant to the         search or recommendation being performed by the MDMS 110.     -   Content item presentation information such as their branding     -   The categories of content they support e.g. general video, news         etc.     -   Content subscription packages and pricing and the rules used to         identify the content items that belong to each subscription         package.     -   Distribution arrangements such as the OEMs or service providers         (collectively termed operators) on whose content receivers their         content is to be made available and/or in which territories         their content can be made available.

The content owner may also wish to configure a content menu application to be made available to the viewer when the viewer is consuming content from that content owner. Again, this content menu registration option may be specified during the initial set-up process or at a later time. The content menu registration option also provides the content owner with the ability to configure specific menu items which access services of the MDMS such as: a search application which allows a viewer to search only within content of that content owner; a content recommendations application which provides a viewer with recommendations from the content of that content owner; quasi-channel applications in which themed content from that content owner is arranged into such quasi-channels either statically or dynamically using pre-defined searches and recommendations which can then be performed without data input from the end viewer; and an advertising application whereby space on the content menu of that content owner can be sold for advertising or can be used to promote specific content from that content owner with the ability to click through the advertising to a piece of content or an interactive destination.

The content owner indicates that the content is configured as they require it to be using the content owner interface of the web-page displayed at their terminal and, upon such indication; the terminal transmits this configuration parameters data via the communications network 104 and network interface 112 to the content owner configuration module 114. Upon receipt of the data, the content owner configuration module 114 sends a confirmation to the content owner terminal that the configuration parameters data has been received and stores the configuration parameters data within its data storage module.

Although described from the viewpoint of a content owner specifying their requirements, a service provider and/or an OEM and/or an end user (e.g. a viewer) could specify their own branding and presentation requirements and menus using the same interface, though the options available for configuration may be different for these different roles.

The data storage module of the content owner configuration module 114 is configured to maintain a database of the content configuration parameters data for retrieval by a content manager 116 which can subsequently apply the content configuration parameters data to content to be transmitted to content receivers.

The MDMS 110 is arranged to retrieve the content metadata configured by the content owners to enable the provision of content search and recommendations to content receivers. The content metadata is retrieved over the communications network by the content indexer 118, optionally as a media RSS XML feed. The content indexer 118 retrieves the content owner feed configurations from the content owner configuration 114, retrieving and processing the content owner feeds as specified. The content indexer 118 augments the metadata retrieved from the content owner with derived data using MOMS rules (such as the appropriate MDMS quality classification and the protocols and codecs implied by the one or more content references) and data derived using the relevant content owner configuration retrieved from the content owner configuration 114 (such as the presentation information, distribution networks and territories and the subscription packages that each content item is associated). The XML metadata for each content item is then passed to a search and retrieval module 120 which indexes and stores the content metadata data in its associated storage.

The received content metadata includes data (e.g. a URL) identifying a location at the content source of the actual content instances to which it relates (with each content instance being associated with a different protocol/codec I bandwidth combination) and thus the search and retrieval module 120 maintains a list of content references for each content item registered by content owners.

A search and recommendations module 122 is arranged as an access layer to the search and retrieval module 120. This exposes a straightforward XML based services API to the content manager 116 for each of the service requests the content manager 116 requires and implements each of these requests utilising one or more of the proprietary APIs and services provided by the search and retrieval module 120.

The MDMS 110 further comprises an identity services module 124 comprising a processor and a user identity storage module. The user identity storage module of the identity services module 124 is configured to store data relating to identities corresponding to different users of a content receiver, e.g. an identity for each individual member of a household. This module provides a user profile data model to be associated with the identities which may comprise:

-   -   nickname     -   personal details including a unique mobile number and/or email         address     -   viewing and content preferences including PIN protection         settings     -   content receivers that this profile is associated with     -   purchased subscriptions and content items     -   content item history     -   content item ratings     -   content item bookmarks and playlist tags

Various user actions on the content receiver initiate communication with the identity service module 124 some of which result in the current users profile being updated by the identity services module 124. Examples of these communications include: editing and saving user details and preferences, viewing bookmarks, bookmarking a content item, rating a content item, viewing a content item etc. A default identity of a content receiver may be tied to a unique identifier of the content receiver itself which is used when no individual identity has been identified. This default identity may be associated with the subscriber details where the content receiver has been provisioned by a service provider.

With this arrangement, profile information of users (including, for example, feedback from their consumption of content) can be used to improve targeting and particularly recommendations of content to specific users. This is achieved by the identity services module 124 creating user profiles in the search and retrieval module 120 and populating these with the content items consumed by each user profile. The search and retrieval module can then make consumption informed user recommendations when requested by the search and recommendations module 122.

In response to reception at the MDMS 110 of an instruction from a content receiver to switch user (such instruction invoked by a user action in relation to the content receiver, i.e. selection of a user associated with the content receiver and optionally the entering of a personal identification number (PIN) code, e.g. via a remote control), the instruction, user identifier, receiver identifier and optional PIN are delivered to the identity services module 124 via network interface 112. The identity services module 124 retrieves the relevant users profile data from its storage module, checks the PIN if required and, if successful, records the new user as the current user for this content receiver in its storage module and generates and returns to the content receiver the user menu appropriate for this user on this content receiver. This new user menu may result in additional requests from the content receiver to the content manager 116 to populate content items (such as the user content recommendations).

When a user of a content receiver wishes to search for specific content and initiates a search via their content receiver to search for such specific content (described later), a search request is received by the network interface 112 via the communications network 104 for the content receiver and delivered to the content manager 116. The content manager 116 then constructs the search query adding a number of additional constraints to the search that are derived from the capabilities and attributes of the content receiver. In particular the content receiver may provide the content receiver identifier, type and operator as part of the search request and the source IP address can be determined from the TCP/IP networking protocols. These are passed to the content receiver profiler 136 which determines and returns:

-   -   The protocols and codecs supported by this type of content         receiver. This data is configured and stored for each type of         content receiver in the content receiver profiler 136. The         dataset for this type of content receiver is retrieved from this         store.     -   The operator associated with this content receiver.     -   The bandwidth capability of this content receiver's network.         This bandwidth would have been submitted to the content receiver         profiler 136 by the content receiver during an earlier bandwidth         test, typically performed on booting the content receiver and         stored by the content receiver profiler against the content         receiver identifier.     -   The determined territory of the content receiver. This is         derived from the source IP of the content receiver using an IP         to geographical location (in this instance, territory) mapping         table.

The content manager 116 then instructs the search and recommendations module 122 to execute the constructed search query. The search and recommendations module 122 extracts the search parameter data from the request in order to address the specific interface of the search and retrieval module 120. The search is then performed by the search and retrieval module 120 as instructed by the search and recommendations module 122 and the metadata of the relevant content items is retrieved and returned to the content manager 116. These search results are then transmitted to the content receiver from which the search request was received. Further details relating to the processing of data for this outgoing transmission will be discussed later.

The effect of the combination of this constrained search query implemented by the content manager 116 against the content metadata augmented by the content indexer 118 is to ensure that only content appropriate for and functional on the content receiver is presented to the user. This process applies to recommendations and other content requests.

When a user of a content receiver instigates a search, any content results returned to the user may optionally be tailored for that user based upon the user's profile. Thus, in this case, the content manager 116, upon receipt of a content request via the network interface 112 adds further constraints to the search query. First it requests the user profile data related to the current user who requested the search to the identity services module 124. The identity services module 124 retrieves the user profile data and returns this to the content manager 116. The content manager 116 amends the search request data to include any relevant profile settings (such as safe search i.e. no adult content) as additional terms in the search query prior to submitting the query to the search and recommendations module 122. Upon reception of such amended search request data, the search and recommendations module 122 proceeds in the manner described above to retrieve the metadata of content items relevant to the search request and these search results are returned to the content manager 116. In addition the content manager 116 may augment the content item metadata returned with relevant user specific metadata such as the user's rating, any user tags, whether or not the user is already entitled to view the content as part of one of their active subscription packages etc. before transmitting the content metadata to the user's content receiver. Thus a personalised form of content presentation can be delivered to the user while still maintaining the requirements and constraints of other parties (i.e. content owner, etc.).

In some instances a further variation of the above scheme may be utilised, particularly when a user has knowledge of the content items being displayed (such as their bookmarked content items), where content items that are not functional on the device are still returned in the results but have their content item metadata further augmented to indicate that they are non-functional content items. This avoids the user thinking that the system has lost content items that they are aware of if they move between content receivers with different capabilities.

The MDMS 110 offers a range of functions to a user of a content receiver which might include, for example: video search and recommendations; interacting with content provider menus; registering new profiles (individual identities); administering payment instruments and billing, transactions and payments authorisation; managing favourites, playlists and history; interacting with messages and other users; and setting up user preferences and options.

A display format for display of the content owner specified and/or personalised form of content on a display screen is delivered to a content receiver from the content manager 116 via network interface 112 and communications network 104. This display format is controlled by the content manager 116 based upon the content configuration parameters data stored in the data storage module of the content owner configuration module 114 and/or the user profile data stored for the current user in the storage module of the identity services 124

The display format is delivered in markup which describes how to display the required functionality of the user interface either via a graphical menu on the TV screen or via a browser application on the content receiver or a third party interactive TV engine.

Communication between the content receiver 108 and MDMS 110 takes place via the content receiver services module 126 which is arranged to service requests from the content receiver 108, enforce security and access controls for protected premium content and may compile XML content responses into a binary representation of XML for efficient communications and processing on the content receiver.

The content receiver services module 126 comprises the following modules: content manager 116 (as hereinbefore described); identity services module 124 (also hereinbefore described); content enforcement module 128; payment services module 130; and image transcoder 132.

The content enforcement module 128 is the element of the content receiver services module 126 configured to gate and authorise the playing of protected (e.g. premium or restricted) content. The content enforcement module 128 operates in conjunction with a payment services module 130, subscription management module 134, the identify services 124 and the content receiver profiler. Such enforcement is implemented by checking territory restrictions, subscription entitlements, informing the user of any gating actions required (e.g. PIN entry required, purchase required, etc.) and requesting authorised content URLs from content owners to provide a content receiver access to a content item. In this regard, a request for a content URL is sent from the content receiver and received at the MDMS 110 via the network interface and forwarded to the content enforcement module 128. The content enforcement module 128 first makes a request to the search and retrieval module 120 for content metadata relating to the content item which the user has requested. The processor of the search and retrieval module 120 retrieves the content metadata from the data storage module of the search and retrieval module 120 and returns the retrieved content metadata to the content enforcement module 128. If the content item is identified as a premium content item the content enforcement module 128 requests the current users subscription entitlements from the subscription management module 134. The subscription management module 134 retrieves and returns the users active subscription entitlements to the content enforcement module 128 and the content enforcement module 128 checks these against the content item subscription packages to determine if the user is entitled to view the content item. If the content item is identified as being restricted by territory the content enforcement module 128 requests the content receiver's territory from the content receiver profiler 136 and checks if the content receiver is entitled to access the content item. Finally the content item is checked to see if it is marked as restricted.

If ail conditions are met and the user is eligible to view the content the URL of the content item is transmitted by the content enforcement module 128, via the network interface 112, to the content receiver. Upon reception of the content URL the content receiver can then retrieve and play the requested content item from the content owner's content source. Optionally the content enforcement module 128 may request a content access authorisation token from the content owner which is transmitted to the content receiver and used by the content receiver when retrieving the content item. This enables the content owner to restrict access to their content to trusted MDMS content receivers.

If, as a result of a determination by the content enforcement module 128 the content requested by a user cannot be viewed by that user then the content enforcement module 128 transmits, via the network interface 112, to the content receiver one of a number of response conditions:

-   -   Subscription required with the subscription offers. The offers         are presented and if one selected a payment process is initiated         by the content receiver against the payment services module 130.         On completion of this process the content URL is re-requested         from the content enforcement module 128.     -   PIN required. The PIN is then submitted with a re-request for         the content URL which is checked by the identity services module         124 before the content URL is returned.     -   Unauthorised content. Access to the content is denied.

When a payment process is initiated against the payment services module 130 the content receiver issues a request to the payment services module 130 which returns for payment details to the content receiver. This causes the content receiver to effect display of a payment details request message on an associated display device. In response to the message a user may have the options of rejecting the request for payment details or accepting the request. If the request is accepted, the user is prompted to enter appropriate payment details which are returned to the payment services module 130 via the communications network 104 and network interface 112. As will be appreciated, the user commands in response to the payment details request may be entered via a user interface device, such as a remote control, of the content receiver.

When payment details data is received, confirmed and successfully processed by the payment services module 130, it transfers the subscription purchased to the subscription management module 134 where it is stored against the current user in the associated subscription storage module. The subscription management 134 also forwards this information to the identity services module 124 to update the user profile data relating to that user to include the subscription package upgrade.

Image transcoder 132 is configured to re-encode images stored in standard web formats (e.g. portable network graphics (PNG), JPEG) to a format supported by any given content receiver. Thus, when image data is transmitted to a content receiver, the image transcoder 132 ensures that such images are supported for display by that content receiver. The content receiver informs the image transcoder the source image URL and what image format it requires. The image transcoder 132 retrieves the source image URL over the network interface 112 and then transcodes the image into one of the required formats before transmitting the transcoded image to the content receiver.

FIG. 4 schematically illustrates a content receiver 108, components thereof and components related thereto. The content receiver 108 receives content via the communications network 104 and broadcast video distribution network 106 and can transmit data to the MOMS 110 via communications network 104. Whilst data paths are illustrated between some elements of the content receiver 108, not all data paths are illustrated for the purposes of clarity.

The content receiver 108 comprises a hardware components layer 138, a OS, drivers and middleware layer 139 and a software applications layer 140. Applications in the OS, drivers and middleware layer 139 and software applications layer 140 are arranged to run on a processor (CPU) 141 of the content receiver 108.

Along with CPU 141, the hardware layer 138 comprises a distribution receiver 142, a network interface 146, a video decoder 143, an audio processor 1430, a graphics processor 144, a content output module 145, a memory component (RAM) 147 and an input receiver 150.

The distribution receiver 142 (such as a tuner for receiving a terrestrial digital television broadcast) receives content at the content receiver 108 from the broadcast video distribution network 106. The data portion of such received content is communicated to the CPU 141 which, in conjunction with an electronic programme guide application (EPG) 148 running thereon, processes EPG data for use by the EPG application

A video portion of the received content from the broadcast video distribution network 106 is decoded using the video decoder 143 which is instructed by the CPU 141 to retrieve video content from the distribution receiver 142 (typically using direct memory access to the RAM 147). The video content is prepared for output on the content display 149 by the content output module 145. The content output module 145 overlays any graphic output required by any of the software applications identified in the software applications layer 140 as output by the graphics processor 144 under instruction from the CPU 141 over the video content and outputs the combined output to the content display.

An audio portion of the received content from the broadcast video distribution network 106 is processed by the audio processor 1430 and output to the content display 149.

Output protocols supported by the hardware of the content receiver 108 may comprise one or more of: High Definition Multimedia Interface (HDMI); Component Video; SCART; Composite Video and audio outputs such as Dolby Digital and stereo analogue,

The OS, drivers and middleware layer 139 comprises a graphics layer module 151, a networking services module 152, an audio services module 153, a personal video recorder (PVR) sub-system module 154, a digital video broadcasting (DVB) stack module (156), a storage services module 156, a system services module 157, and an operating system application 161 and drivers 162. These modules are conventional features on many content receivers (such as set-top boxes). Further description of these modules will therefore only be provided where necessary in relation to the functioning of one or more embodiments of the present invention.

Input receiver 150 is arranged to receive commands for controlling the content receiver 108, such commands being input by a user by way of an input device 158. The commands may be entered using, for example, a set-top box remote control device through which commands are entered by the user by pressing specific keys of the remote control device. A control signal from the remote control is transmitted to the content receiver 108 by any suitable means, e.g. infra-red transmission.

The software applications layer 140 of the content receiver 108 comprises: an EPG module 148 (referred to above); a browser application 159; and a media display management module application (MDMM) 160.

Although a browser application is shown in the illustrated embodiment, other suitable interactive display engines may be used, e.g. a flash engine or SVG engine.

The MDMM 160 runs on the CPU 141 and configures the CPU 141 for communication (via network interface 146) with the MDMS 110 in order to manage content received at the content receiver 108 over the communications network 104. Commands input by a user requesting delivery of a content item to the content receiver 108 are received at the input receiver 150 and communicated to CPU 141 which implements the MDMM 160 to request content data appropriate to the command from the MDMS 110.

Where the CPU 141 instructs the video decoder 143 and audio processor 1430 to process video received over the communications network 104 via the network interface 146 this will be marshalled by the CPU 141 in RAM 147 and then the video and audio portions will be retrieved by the video decoder 143 and audio processor 1430 using DMA in the same manner as when the video was received over the broadcast video distribution network 106 via the distribution receiver 142.

CPU 141 also implements MDMM 160 to manage and control content received at the content receiver 108 over the broadcast video distribution network 106.

FIG. 5 shows a screenshot 170 of a screen displayed by a content navigation module when invoked by a user. In a particular example, the user may enter commands to initiate navigation to such a module. For instance, a viewer menu module may be invoked, for example, by a user pressing a “Left” button on a remote control when viewing broadcast TV content, and a viewer content navigation module is then reached by way of a further keypress (e.g. selecting an item in the menu). A branded content owner menu may be invoked, for example, by a user pressing a “Right” button on a remote control when viewing broadcast TV content. A branded content owner content navigation module is then reached by way of a further keypress (e.g. selecting an item in the menu). Alternatively, the content navigation module could be invoked directly e.g. pressing a “Red” button on a remote control.

Although this example relates to a content navigation module, other modules or menus (e.g. content owner, content receiver, and viewer menus, mini content guide (related to content currently being viewed) and expanded content guide (again related to content currently being viewed)) are envisaged and these may be navigated to using similar user input commands on a remote control. How these different capabilities are designed and invoked and when they are made available to the user forms a key part of the orchestration of competing parties aspirations in the user interface. For example a content owner menu may be available by pressing the “Right” button on the remote control when watching a content item. The particular content menu displayed is determined by the rules of the MDMM 160 to be the content menu for the currently active content item.

Template data for the content navigation module screen illustrated in FIG. 5 is stored in the data storage module of content owner configuration module 114 of the MDMS 110. The template data is populated by the configuration parameters data (described above) stored in the data storage module and so the format of the content navigation module screen will vary for different Operators, content providers and OEM contexts because these will all have specified different configuration parameters data. The template data, however represents a the configuration options available and when combined with particular configuration parameters data specifies a particular instance of the content navigation module as specified by a particular party,

A content navigation module initiation command input by a user is received by the CPU 141 which implements the MDMM 160 to request template data for the content navigation module screen from the MDMS 110. This template data is retrieved from the data storage module of content owner configuration module 114 of the MDMS 110 and sent to the communications network via the network interface 112. The content receiver 108 receives the template data via network interface 146. The CPU 141 instructs the graphics processor 144 to retrieve and render overlay graphics from the RAM 147 and these overlay graphics are combined with template data in the content output 145 for processing for display of the content navigation module on the content display 149.

The content navigation module may be embedded as sub-content (i.e. a sub-image) in content received at the content receiver and which content navigation module can be invoked whilst viewing the content by entering an appropriate command via a user input device 158. The content navigation module may also be treated as stand-alone content which need not be invoked whilst viewing content, but which can be invoked whilst performing any operation on the content receiver.

The screen of the content navigation module contains a search term entry field 172, a list of popular search terms 174, a virtual keyboard 176 and an instructions field 177.

A user may populate the search term entry field 172 using commands input via a user input device (such as a TV or set-top box remote control). By performing presses or multiple presses of numeric keys on the remote control (in a manner similar to character entry when creating text of an SMS) a user can enter alphanumeric characters in the search term entry field 172. A delete function may be assigned to a specific key (e.g. a left arrow key) to allow a user to delete characters if errors are made.

The virtual keyboard 176 can also be used to select alphanumeric characters in order to populate the search term entry field 172. A cursor comprising a movable indication or pointer feature can be used to denote which of the search term entry field 172, list of popular search terms 174, or virtual keyboard is currently, or is to be in use. In order to switch between the search term entry field 172 and the virtual keyboard 176, the user may invoke such a switch by pressing an appropriate key on the remote control having a switch function assigned thereto (e.g. a right arrow key) to move the cursor from the search term entry field to the virtual keyboard 176. A particular alphanumeric character (e.g. the letter “A”) of the virtual keyboard 176 may be the default character indicated by the cursor when the virtual keyboard 176 is invoked. Navigation of the cursor around the keyboard is achieved by way of remote control keys having appropriate movement functions assigned thereto (e.g. Up, Down, Left, Right arrow keys). A conventional TV or set-top box remote control may be suitable. When a desired character has been reached, it is added to the search term entry field 172 by pressing a remote control key having an appropriate select function assigned thereto (e.g. Select key).

During the population process, the user commands are received by CPU 141 of the content receiver. The CPU 141 instructs the graphics processor 144 to retrieve overlay graphics data from the RAM 147 and these are passed to the content output 145 for updating the display.

In the illustrated embodiment, letter characters are the only type of alphanumeric characters shown on the virtual keyboard 176. However, the virtual keyboard may have a “123” icon which can be selected to transform the alphabetical keyboard to a numeric keyboard. When in the numeric keyboard state, the “123” icon will be replaced by an “ABC” icon to allow return to the alphabetic keyboard. In the same manner, different language (e.g. character sets such as Arabic or Hebrew) virtual keyboards can be supported as required by the operator, user, OEM or content owner configurations.

Aside from alphabetic and numeric characters and icons for switching between virtual keyboards appropriate to each, there are also displayed “Space”, “Delete” and “Search” icons, with selection of the “Space” function implementing corresponding insertion of a space between characters in the search term entry field 172, and selection of the “Delete” function implementing deletion of a character in the search term entry field 172. Selection of the “Search” function executes a search for content based upon a search term entered in the search term entry field 172. The CPU 141, configured by the MDMM 160, sends a search request to the network interface 146 for transmission via the communications network 104 to the MDMS 110. The search request is received at the network interface 112 of the MDMS 110 and transferred to the content manager 116. Content manager 116 requests data from the search and recommendations module 122 based upon the data in the search request indicating the input search terms. The search and recommendations module 122 addresses search and retrieval module 120 to locate appropriate content data identifier items. If relevant content data identifier items are located by the search and recommendations module 122, these are transmitted to the content manager 116. The content manager 116 requests configuration parameters data for the content data identifier items from the data storage module of content owner configuration module 114. These are located and returned to the content manager 116 which forwards both the content data identifier items found as a result of the search and the configuration parameters data to the network interface 112 for transmission to the content receiver 108. The content data identifier items found as a result of the search and the configuration parameters data are received at the content receiver by the network interface 146 and transferred to the CPU 141 which instructs the graphics processor 144 to retrieve overlay graphics data from the RAM 141. The retrieved overlay graphics data is then passed to the content output 145 which processes the content data identifier items and updates the display screen data. Such display screen data, updated with the search results (i.e. the content data identifier items) is passed to the content display 149 to display the content navigation module populated with the search results.

The list of popular search terms 174 comprises a list of a plurality (e.g. twenty) of the most popular search terms, where the list is determined by characters entered in the search term entry field 172. As characters are populated in the search term entry field 172, the list of popular search terms 174 is updated. For example, if a user populates “A” in the search term entry field 172 then the list will contain a plurality of the most popular search terms beginning with the letter A. Such population proceeds via the same process as described above in relation to the display of search results.

The user can navigate the list using remote control keys having appropriate movement functions assigned thereto (e.g. Down and Up arrow keys) and can select a search term from the list to populate the search term entry field 172 by using, for example, a Select key of the remote control.

The list of popular search terms 174 may be arranged with most popular terms at the top thereof and with lower terms being of decreasing popularity.

Where no search term is populated in the search term entry field 172, then as a default, the list of popular search terms 174 may comprise, for example, the twenty “Most Popular” search terms. These may be relevant to the user's profile, for example, based on age, language, or location.

The instructions field 179 includes instructions to a user for implementing functions of the content navigation module. In the illustrated example screenshot 170 it is indicated 178, 179 that a particular key of the remote control having an appropriate function assigned thereto (e.g. Red key) can initiate the search, and a different key of key of the remote control having an appropriate function assigned thereto (e.g. Green key) should be pressed to allow the user to access their saved searches.

FIGS. 6a and 6b show screenshots 180 of an example search results screen displayed by the content navigation module to show results of a search invoked by the user. The exact layout, functionality and branding of this screen would be determined by the OEM, operator and content owner configurations as well as user preference configurations.

The search results screen of the content navigation module contains a search term field 182, a list of content identifier items 184, a cursor 186 (shown in FIG. 6a but not in FIG. 6b ), categories under which the search results were found 188, filtering options 190, an associated content list 192, an associated content list cursor 193 (shown in FIG. 6b but not in FIG. 6a ) and an options field 194.

The search terms entered by the user of the content receiver using the content navigation module described above in relation to FIG. 5 are displayed in the search term field 182. The user has the option of using search filters selected from the filtering options 190 to refine their search results and, in doing so, each selected search filter will be populated alongside the search terms entered by the user. Thus a search modified from the user's initially entered search terms may appear in the form “Search name+1^(st) filter applied+2^(nd) filter applied” and which modified search term is then used to obtain updated search results from a content feed.

The filtering options 190 are arranged as a list of category refinements, e.g. Content Type (such as Music, Movies, User generated content, TV programmes), Quality, Content Provider, Genre, Sort results, Language, User tagged content, and Reset all filters. A number may be displayed against each category refinement and to which a correspondingly numbered key on a remote control of the content receiver will, when pressed, invoke the display of a host of sub-categories related to the selected category to allow the user to further refine the search results.

In the illustrated example of FIGS. 6a and 6b , if the user presses the “6” key for the “Quality” category, the filter list changes to show sub categories such as High Definition (HD), Standard Definition (SD), and both HD and SD. If, for example, the user selects the HD sub-category, an indication is displayed adjacent the “Quality” filtering option on the main category refinements list of filtering options 190 to indicate that there is category refinement under the “Quality” filtering option. The search term field 182 is updated to include “HD” in the modified search term.

The list of content identifier items 184 comprises a vertical list of identifier items relating to content found through the search. As a default, the identifier items are arranged with the most relevant identifier items at the top of the list. The content identifier items provide at least a name of the content (e.g. Title) and serve as links to the content they identify. Thus, if a user selects a particular content identifier item, the content will then be displayed to the user. An input command received by the user input is communicated to the CPU 141 which determines if the requested content is available via the broadcast video distribution network or the communication network. If available via the broadcast video distribution network, the CPU 141 sends a control signal to the distribution receiver 142 to ensure that an appropriate gateway is open (e.g. correct TV channel selected) to receive the content at the content receiver. Additionally, the CPU 141 sends a notification to the content manager 116 of the MOMS 110 via the communications network that such content is being obtained. The content manager 116 communicates with the data storage module of the content owner configuration module 114 to locate appropriate parameters to be applied to the content and, upon location, transfers the same to the content receiver 108 via the communications network. Upon receipt of the content at the distribution receiver 142 of the content receiver 108, the content passes to the video decoder which applies the parameters received from the MDMS 110 to the content.

If the content is available via the communication network, a content request is sent by the CPU 141 via the network interface 146 to the communication network 104 for transmission to the MDMS 110. Upon receipt of the request, the network interface 112 transfers the request to the content manager 116 which acquires location data (e.g. a URL) of the requested content from the content indexer 118 (via the content owner configuration module 114) and returns the location data of the content source via the communications network 104 to the content receiver 108. The CPU 141 upon receipt of the location data then requests the content from a content source using the location data.

Cursor 186 (as illustrated in FIG. 6a , but not FIG. 6b ) comprises a movable indication feature which highlights one content identifier item in the list of content identifier items 184. The cursor is movable vertically from a first position where a first content identifier item is highlighted to a second adjacent position where a second content identifier item is highlighted responsive to user input via the remote control (e.g. Up/Down keys of the remote control).

When the cursor 186 is located over a content identifier item, the highlighted item may be enlarged (compared with other content identifier items in the list of content identifier items 184) and/or gain a border. Additionally, further information relating to the content may be displayed within the content identifier item (e.g. Quality (HD/SD), Premium Icon (to indicate that payment is required to view the content), age certificate icon, a content owner logo, content length, whether the content is broadcast video or Internet video content, and one line synopsis of content).

The content identifier items may comprise one or more of: image data; video data; and text data. The image data may comprise images and/or icons in a particular format e.g. JPEG.

The cursor 186 may also comprise a directional indicator to indicate to a user that the list can be navigated using Up/Down arrows of the remote control. If the cursor is positioned over the first item in the list only a down indicator should be visible and, likewise, if the cursor is positioned over the last item in the list, only an up indicator should be visible.

The, categories under which the search results were found 188 may include categories such as “Local”, “General”, “News” and “Adult”. A number associated with each category indicates the number of content items found in the search under that particular category. The actual categories displayed may be dynamically determined by the MDMS based on the results listed.

Associated content list 192 comprises a horizontal list arranged below the list of content identifier items 184, and which includes content items associated with the content identifier item currently highlighted in the list of content identifier items 184. The associated content list 192 is a dynamic list which changes as the content identifier item highlighted in the list of content identifier items 184 changes. The content identifier items of the associated content list 192 serve as links to the content they identify. Thus, if a user selects a particular content identifier item, the content will then be displayed to the user.

In the illustrated example, the content identifier items in the associated content list 192 are recommendations based upon the highlighted item in the list of content identifier items 184. Further, the associated content list is, in the illustrated example, in a carousel arrangement.

To access the associated content list 192 from a list of content identifier items 184 a user presses remote control keys having appropriate movement functions assigned thereto (e.g. Left/Right arrow keys) to move focus to the associated content list 192. In a particular arrangement, pressing a Left/Right arrow key once will shift focus to the associated content list 192, the list of content identifier items 184 will fade, the cursor 186 will disappear and the screen displayed will be that as illustrated in FIG. 6b . Pressing up/down arrow keys will shift focus back to the list of content identifier items 184, the associated content list 192 will fade and the screen will revert to the display illustrated in FIG. 6 a.

Associated content list cursor 193 (illustrated in FIG. 6b but not 6 a) only appears when focus is changed to the associated content list in the manner described above. The associated content list cursor 193 comprises a movable indication feature which highlights one associated content identifier item in the associated content list 192. The cursor is movable horizontally from a first position where a first associated content identifier item is highlighted to a second adjacent position where a second associated content identifier item is highlighted responsive to user input via the remote control (e.g. Left/Right keys of the remote control).

When the associated content list cursor 193 is located over a content identifier item, the highlighted item may be enlarged (compared with other associated content identifier items in the associated content list 192) and/or gain a border. As a default option in a particular arrangement, the centre item of the associated content list 192 is the item highlighted by the associated content list cursor 193. Pressing the Left/Right keys rotates the carousel but the highlighted item remains in the centre, i.e. the cursor remains stationary at the centre of the associated content list 192 whilst the items move relative to it.

Additionally, further information relating to the associated content item currently highlighted may be displayed within the associated content identifier item (e.g. a content owner logo, one line synopsis of content).

The associated content list cursor 193 may also comprise a directional indicator to indicate to a user that the list can be navigated using Left/Right arrows of the remote control. In the illustrated example, the list is arranged in a carousel manner, and so both directions are indicated at all times.

The additional options field 194 presents further functions that can be performed. In the illustrated example screenshot 180 it is indicated that a particular key of the remote control having an appropriate function assigned thereto (e.g. Red key) should be pressed to perform a new search, and a different key of the remote control having an appropriate function assigned thereto (e.g. Green key) should be pressed to allow the user to bookmark the highlighted item in the list. Further options might include the illustrated functions of a rating function (e.g. “Love this”) and “Save”. The “Love this” function allows a user to rate the highlighted item in the list by pressing a Yellow key of the remote control and the “Save” function allows the user to save the search results by pressing the Blue key of the remote control.

Content items in the list may optionally display a number of relevant focusable content sub-items arranged vertically, for example, options to play SD or HD and to remove the item from the list.

FIG. 7 illustrates steps of a procedure in the content navigation module to provide access to additional content either during playback of content (e.g. video sequences) on a content receiver or from another application (e.g. from a content receiver menu, viewer menu or content provider menu).

If the user wishes to invoke a content navigation module, the user may initiate the content navigation module on the content receiver (S700), for example by pressing a button (such as a Red button) on an input device (e.g. remote control). When the content receiver accepts input from the user that indicates the content navigation module should be started, the content receiver contacts the MDMS 110 to indicate that a content navigation module has been invoked. Referring also to FIG. 4, the input receiver 150 forwards data to the MDMM 160 running on CPU 141 indicating that the content navigation module has been invoked. The CPU 141 sends a request for content navigation module display data to the network interface 146 for onward transmission to the MDMS 110 via communication network 104. The request is received in the network interface 112 of the MDMS 110 and forwarded to the content manager 116. The content manager 116 requests the content navigation module display data from the data storage module of the content owner configuration module 114 which locates such content navigation module display data and returns the same to the content manager 116. The content manager 116 passes the content navigation module display data to the network interface 112 for transmission via the communications network 104 to the content receiver 108. Such content navigation module display data is received at the network interface 146 of the content receiver 108 and then passed to the CPU 141 implementing MDMM 160. The MDMM 160 renders the specified content navigation module using the graphics processor 144. The graphics output is then forwarded to the content output 145 and the content navigation module is displayed on the content display 149 (S702). The content navigation module is displayed, for example by overlaying the graphics of the content navigation module over dynamic video content (e.g. either wholly or in a transparent format) or presenting the graphics of the content navigation module as a stand alone image without any content (dynamic or otherwise) behind. The content navigation module may also be presented in a box wrapped around the video (e.g. an L-shaped box) with the video content still playing.

At this point, the user can choose between entering characters themselves to form a search term, or selecting predefined or pre-saved search search terms (S704). If a predefined search is selected from available options displayed on screen (S7040), the process jumps directly to the search for content (S710) described later. However, if a user chooses to enter search terms themselves, then these may be entered by the user using an available input device (e.g. remote control), the received characters forming a user search term (S706). Command data received at the input receiver 150 from the characters input via the input device 158 is forwarded to the CPU 141. Input character data is forwarded to the graphics processor 144 where the input character data is encoded and forwarded from the graphics processor 144 to the content output 145 to allow the content navigation module screen displayed on the content display 149 to be updated as characters are entered.

When character entry is complete and the search term has been compiled, the user indicates such and requests a search by entering a command through the input device 158. For example, inputting a control signal such as activating the “Run Search” user actuable icon. The MDMM 160 determines that the search has been requested and responds by forwarding the user search term data in a search request to the network interface 146 for onward transmission to the MDMS 110 via communication network 104 (S708). Network interface 112 of the MDMS 110 receives the request and forwards it to the content manager 116 which transfers the search term data to the search and recommendations module 122 to initiate a search (S710). The search and recommendations module runs the search query and retrieves the content item metadata for the search results and returns these to the content manager 116.

The content manager 116 then outputs the content item metadata to the network interface 112 for transmission via the communications network 104 to the content receiver 108 (S712). This data is received at the network interface 146 of the content receiver 108 and then passed to the CPU 141 running the MDMM 160 application which renders the search results in a search results page as previously described in relation to FIG. 6 using the graphics processor 144. The graphics output is then forwarded to the content output 145 and the content navigation module is displayed on the content display 149 (S714).

At this point, the user may wish to view an item of content returned in the search results or refine the search by indicating that search filters are to be applied (S716). If the user selects one or more search filters (S7160) to tailor the search as required (these are illustrated under reference numeral 190 in FIG. 5), these filter terms are added to the existing search terms (S7162) and the process returns to step 8710 in order for the search to be conducted again.

If no filtering is required, the user can select a content item to view (S718) by entering a command through the input device 158. When a view content request is entered through the input device 158, the CPU 141 is notified by the input receiver 150 that a request has been received to view content, CPU 141 proceeds to forward a request for the requested content in a content request to the network interface 146 for onward transmission to the MDMS 110 via communication network 104 (S718). The request is received in the network interface 112 of the MDMS 110 and forwarded to the content enforcement module 128 which checks the entitlement of the user and content receiver to view the content (as previously described) and returns the content URL to the MDMM 160 application on the content receiver 108 via the communication network 104 (8720). The MDMM application then makes a request to the content source specified in the content URL via the network interface 146 and communications network 104 (S722).

The content source receives the request for content and retrieves such content for return to the content receiver 108. The content is transmitted via the communications network 104 and received in the network interface 146 of the content receiver 108 (S724). This data is retrieved by the CPU 141 and then passed to the video decoder 143 and audio processor 1430. The video decoder 143 renders the content for display and the content is then passed to the content output 145 to allow the content to be displayed on the content display along with the audio output (S726).

In a particular arrangement, the list of content identifier items may be ordered by relevance depending on how closely the content item matches the search terms. The ordering may also relate to the user's profile, for example, based on age, language, or location.

In the above arrangement, when content is requested from a list of search results, the request for content is processed in the content enforcement gateway before being passed to the content source. However, when content enforcement is not required for a content item, the content URL could be included for each item in the search results so that the MDMM 160 does not have to query the MDMS 110 to determine the content URL.

FIG. 8 shows a screenshot 196 of a screen displayed by a playlist module when invoked by a user. A playlist comprises a list of content identifier items 200 comprising links to content. The playlist is created by a user and is stored in the data storage module of MDMS 110.

The playlists screen of the playlist module contains a module identifier field 198, a list of content identifier items 200, a cursor 202, an associated content list 204, an associated content list cursor 206 and an options field 208.

The type of module (in this case “playlist”) is displayed in the module identifier field 198.

The list of content identifier items 200 comprises a vertical list of identifier items relating to content in the playlist. The content identifier items provide at least a name of the content (e.g. Title) and serve as links to the content they identify. Thus, if a user selects a particular content identifier item, the content will then be displayed to the user using processes in a similar manner as described above.

Cursor 202 comprises a movable indication feature which highlights one content identifier item in the list of content identifier items 200. The cursor is movable vertically from a first position where a first content identifier item is highlighted to a second adjacent position where a second content identifier item is highlighted responsive to user input via the remote control (e.g. Up/Down keys of the remote control).

When the cursor 202 is located over a content identifier item, the highlighted item may be enlarged (compared with other content identifier items in the list of content identifier items 200) and/or gain a border.

Additionally, further information relating to the content may be displayed within the content identifier item (e.g. Quality (HD/SD), Premium Icon (to indicate that payment is required to view the content), age certificate icon, a content owner logo, content length, and one line synopsis of content).

The content identifier items may comprise one or more of: image data; video data; and text data. The image data may comprise images and/or icons in a particular format e.g. JPEG.

The cursor 202 may also comprise a directional indicator to indicate to a user that the list can be navigated using Up/Down arrows of the remote control. If the cursor is positioned over the first item in the list only a down indicator should be visible and, likewise, if the cursor is positioned over the last item in the list, only an up indicator should be visible.

Associated content list 204 comprises a horizontal list arranged below the list of content identifier items 200, and which includes content items associated with the content identifier item currently highlighted in the list of content identifier items 200. The associated content list 204 is a dynamic list which changes as the content identifier item highlighted in the list of content identifier items 200 changes. The content identifier items of the associated content list 204 serve as links to the content they identify. Thus, if a user selects a particular content identifier item, the content will then be displayed to the user.

In the illustrated example, the content identifier items 200 in the associated content list 204 are recommendations based upon the highlighted item in the list of content identifier items 200. Further, the associated content list is, in the illustrated example, in a carousel arrangement.

To access the associated content list 204 from a list of content identifier items 200 a user presses keys of a remote control having appropriate movement functions assigned thereto (e.g. Left/Right arrow keys) to move focus to the associated content list 204. In a particular arrangement, pressing a Left/Right arrow key once will shift focus to the associated content list 204 and the list of content identifier items 200 will fade, and pressing up/down arrow keys will shift focus back to the list of content identifier items 200 and the associated content list 204 will fade.

Associated content list cursor 206 comprises a movable indication feature which highlights one associated content identifier item in the associated content list 204. The cursor is movable horizontally from a first position where a first associated content identifier item is highlighted to a second adjacent position where a second associated content identifier item is highlighted responsive to user input via the remote control (e.g. Left/Right keys of the remote control).

When the associated content list cursor 206 is located over a content identifier item, the highlighted item may be enlarged (compared with other associated content identifier items in the associated content list 204) and/or gain a border. As a default option in a particular arrangement, the centre item of the associated content list 204 is the item highlighted by the associated content list cursor 206. Pressing the Left/Right keys rotates the carousel but the highlighted item remains in the centre, i.e. the cursor remains stationary at the centre of the associated content list 204 whilst the items move relative to it.

Additionally, further information relating to the associated content item currently highlighted may be displayed within the associated content identifier item (e.g. a content owner logo, one line synopsis of content).

The associated content list cursor 206 may also comprise a directional indicator to indicate to a user that the list can be navigated using Left/Right arrows of the remote control. In the illustrated example, the list is arranged in a carousel manner, and so both directions are indicated at all times.

Although FIG. 8 illustrates cursor 202 and associated content list cursor 206 present at the same time, this need not be the case. Indeed, in an optional arrangement, when focus is on list of content identifier items 200, then only the cursor 202 is displayed. However, when focus changes to the associated content list 204, the cursor 202 disappears and the associated content list cursor 206 appears around an item in the associated content list 204. When focus changes back to the list of content identifier items 200, the cursor 202 reappears and the associated content list cursor 206 disappears. This arrangement is similar to that described in relation to FIGS. 6a and 6 b.

The additional options field 208 presents further functions that can be performed. In the illustrated example screenshot 180 it is indicated that a particular key of the remote control having an appropriate function assigned thereto (e.g. Red key) should be pressed to perform a search, and a different key of the remote control having an appropriate function assigned thereto (e.g. Green key) should be pressed to allow the user to bookmark the highlighted item in the list. Further options might include the illustrated functions of “Love this” and “Save”. The “Love this” function allows a user to rate the highlighted item in the list by pressing a Yellow key of the remote control and the “Save” function allows the user to save the search results by pressing the Blue key of the remote control.

FIG. 9 shows a screenshot 210 of a screen displayed by a TV guide module when invoked by a user.

The TV guide screen of the TV guide module contains an information field 212, a list of TV programme content identifier items 214, a cursor 216, an associated content list 218, an associated content list cursor 220 and an options field 222.

The information field 212 displays, for example, the viewer logged in at the content receiver, a number of the viewer's friends currently online versus a total number of friends, a number of unread messages in the viewer's inbox, and a current date and time.

The list of TV programme content identifier items 214 comprises a vertical list of identifier items relating to content being broadcast in relation to the channel currently being viewed. In a particular example, the current programme is shown along with subsequent programmes on that channel.

As will be appreciated, there is no point in showing previous programmes in a linear broadcast environment, unless “catch-up” services are available via the communications network or PVR services since the opportunity to view previous programmes has passed. The content identifier items 214 provide at least a name of the content (e.g. programme title) and serve as links to the content they identify. Thus, if a user selects a particular content identifier item 214, the content will then be displayed to the user using processes in a similar manner as described above. The content identifier items 214 may further include metadata providing a synopsis of the programme, a content owner logo, an information icon, and a start time (if the programme has not yet started).

Cursor 216 comprises a movable indication or pointer feature which highlights one content identifier item 214 in the list of TV programme content identifier items 214. The cursor 216 is movable vertically from a first position where a first content identifier item is highlighted to a second adjacent position where a second content identifier item is highlighted responsive to user input via the remote control (e.g. Up/Down keys of the remote control).

When the cursor 216 is located over a content identifier item, the highlighted item may be enlarged (compared with other content identifier items in the list of content identifier items 200) and/or gain a border.

The content identifier items 214 may comprise one or more of: image data; video data; and text data. The image data may comprise images and/or icons in a particular format e.g. JPEG.

The cursor 216 may also comprise a directional indicator to indicate to a user that the list can be navigated using Up/Down arrows of the remote control. If the cursor is positioned over the first item in the list only a down indicator should be visible and, likewise, if the cursor is positioned over the last item in the list, only an up indicator should be visible.

Associated content list 218 comprises a horizontal list arranged below the list of TV programme content (or online media content (depending on the configuration)) identifier items 214, and which includes content items associated with the content identifier item currently highlighted in the list of TV programme content identifier items 214. The associated content list 218 is a dynamic list which changes as the content identifier item highlighted in the list of TV programme content identifier items 214 changes. Depending on the configuration (OEM, Operator or Content Owner (broadcaster), the content identifier items 214 could relate to “catch-up” TV items, online content items from one or more pre-defined sources, related broadcast shows or channels from the same broadcaster). The content identifier items of the associated content list 218 serve as links to the content they identify. Thus, if a user selects a particular content identifier item, the content will then be displayed to the user.

In the illustrated example, the content identifier items in the associated content list 218 are recommendations based upon the highlighted item in the list of TV programme content identifier items 214. Further, the associated content list is, in the illustrated example, in a carousel arrangement.

To access the associated content list 218 from a list of TV programme content identifier items 214 a user presses remote control keys having appropriate movement functions assigned thereto (e.g. Left/Right arrow keys) to move focus to the associated content list 218. In a particular arrangement, pressing a Left/Right arrow key once will shift focus to the associated content list 218 and the list of content identifier items 214 will fade, and pressing up/down arrow keys will shift focus back to the list of TV programme content identifier items 214 and the associated content list 218 will fade.

Associated content list cursor 220 comprises a movable indication feature which highlights one associated content identifier item in the associated content list 218. The cursor 216 is movable horizontally from a first position where a first associated content identifier item is highlighted to a second adjacent position where a second associated content identifier item is highlighted responsive to user input via the remote control (e.g. Left/Right keys of the remote control).

When the associated content list cursor 220 is located over a content identifier item, the highlighted item may be enlarged, or display another pre-programmed visual effect (for example a video thumb-nail) depending on the device capabilities, and OEM, operator or content owner configuration (compared with other associated content identifier items in the associated content list 218) and/or gain a border. As a default option in a particular arrangement, the centre item of the associated content list 218 is the item highlighted by the associated content list cursor 220. Pressing the Left/Right keys rotates the carousel but the highlighted item remains in the centre, i.e. the cursor remains stationary at the centre of the associated content list 218 whilst the items move relative to it.

Additionally, further meta-data information relating to the associated content item currently highlighted may be displayed within the associated content identifier item (e.g. a content owner logo, one line synopsis of content).

The associated content list cursor 220 may also comprise a directional indicator to indicate to a user that the list can be navigated using Left/Right arrows of the remote control. In the illustrated example, the list is arranged in a carousel manner, and so both directions are indicated at all times.

Although FIG. 9 illustrates cursor 216 and associated content list cursor 220 present at the same time, this need not be the case. Indeed, in an optional arrangement, when focus is on list of content identifier items 214, then only the cursor 216 is displayed. However, when focus changes to the associated content list 218, the cursor 214 disappears and the associated content list cursor 220 appears around an item in the associated content list 218. When focus changes back to the list of content identifier items 214, the cursor 216 reappears and the associated content list cursor 220 disappears. This arrangement is similar to that described in relation to FIGS. 6a, 6b and 8.

The additional options field 222 presents further functions that can be performed. In the illustrated example screenshot 210 it is indicated that a particular key of the remote control having an appropriate function assigned thereto (e.g. Red key) should be pressed to perform a search.

The particular functions available (for example, “record”, “bookmark”, “share” or “download”), will depend on the device's capabilities and the OEM, operator or content owner preferences.

Although described in relation to a TV programme guide, the arrangement of FIG. 9 may also be applicable as a content guide for content received via the communications network rather than broadcast content.
